U ni form Tire Q ua lity G radin g
is a tire information system developed by the United States National
Highway Traffic Safety Administration (N HTSA) that is designed to
help buyers make re lative comparisons among tires. The UTQG is
not a safety rating and not a guarantee that a tire will last for a
prescribed number of miles or perform in a certain way. It simply
gives tire buyers additiona l information to combine with other
considerations, such as price, brand loya lty and dealer recommen- dations
. Under UTQG, tires are graded by the tire manufacturers in
three areas : treadwear, trac tion and temperature resistance. The
U TQG information on the tires, molded into the sidewalls.
U .S . DOT Tire Identifi cation Number (TIN )
This is the tire's "serial number" It begins with the letters "DOT" and
indicates that the ti re meets a ll federa l standards. The next two
numbers or letters indicate the plant where it was manufactured,
and the last four numbers represent the week a nd year of manufac ­
ture . For example,
DOT ... 2209 ...
means that the tire was produced in the 22t h week of 2009. The
other numbers are marketing codes that may or may not be used by
t he tire manufacturer. This information is used to contact
consumers if a tire defect requires a recall.

Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle.
Fig. 148 Tire pressure
label: located
on
driver 's side B-pillar
Tire pressure generally refers to the amount of air in a tir e that it
needs it to do its job and safely carry the combined load of the entire
vehicle and its contents. Tire pressure is measured in kilopascals
(kPa), the international measuring unit and in pounds per square
inch (PSI). Tire pressure is based in part on the vehicle's design and
load limit -the greatest amount of weight that the vehicle can carry
safely and the tire size. The proper tire pressure is frequently
referred to as the "recommended cold tire inflation pressure." Air in
the tires expands when the tire heats up because of internal friction
when it flexes in use. The tire pressure is higher when the tire has
warmed up than when it is "cold ." It is the inflation pressure in a
"cold" tire that counts. Therefore, you should never let air out of a
warm tire to match "cold tire inflation pressure" recommendations .
The tires would then be underinflated and could fail suddenly.

Maintaining proper tire pressure is one of the most important
things you can do to help avoid sudden tire failure . Underinflated
tires are a major cause of sudden tire failure. Keeping tires at the
right pressure is also important for safe and responsive vehicle
handling, traction, braking and load carrying .
Tire pressures are
particularly important when the vehicle is being driven at higher
speeds, and then especially when heavily loaded even within the
permissible load -carrying capacities approved for your vehicle.
The recommended tire pressures for your Audi depend on the kind
of tires on your vehicle and the number of passengers and/or
amount of luggage you will be transporting .
Th e tire pressure label located on driver's side 8 -pillar on your Audi
lists the recommended cold tire inflation pressures for the vehicle
at its maximum capacity weight and tires that were on your vehicle

Because technica l changes may be made to vehicle equip ment
during the mode l year, always compare the tire size designat ion on
the tire pressure la bel on y our vehicle with the tires on your vehicle.
Make sure tha t the t ire size information on the veh icle labe l is the
same as the size of the tires on the vehicle. Th is is especially impor ­
t ant if the vehicle belongs to someone e lse or you boug ht the

& WARNING
Overloading a vehi cle can cause loss of vehicle control , a crash or
other accident, serious personal injury, and even death .
• Carrying more weight th an your vehicle was de signed to carry
will prevent the vehicle from handling properly and increase the
risk of a loss of vehicle control.
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe distance .
• Tires on a vehicle that has been overloaded c an fail suddenly
causing loss of control and a crash .
& WARNING
• Incorrect tire pressures and/or underinflation can lead to a
s erious o r fatal a ccident .

& WARNING (continued)
• Incorrect tire pressures and/or underinflation cause increased
tire wear and can affect the handling of the vehicle.
• Incorrect tire pressures and/or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehicle control. •
Checking tire pressure
The correct tire pressure for the tires originally installed
on your vehicle is listed on the tire pressure label located
on driver's side 8-pillar.
The recommended tire pressures are on the tire pressure label and
in the table=>
page 238, "Cold tire inflation pressure". This means
that the pressure must be checked and adjusted when the tire has
not been driven for more than a couple of miles (kilometers) at low
speeds during the previous three hours. Air in the tires expands
when the tire heats up as a result of internal friction as it flexes in
use. The tire pressure is higher when the tire has warmed up than
when it is "cold."
It is the inflation pressure in a "cold" tire that counts. Therefore, you
should never let air out of a warm tire to match "Cold tire inflation
pressure" recommendations =>
page 238. The tires would then be
underinflated and could fail suddenly.
The tire pressure label on your Audi lists the recommended cold tire
inflation pressures for the new, original equipment tires that were
on your vehicle at the time it was manufactured . For the location of
the label =>
page 238, fig. 148.
Most tires lose air naturally over time. They can also lose some air if
you drive over a pothole or hit a curb while parking. It is usually not
possible to see whether the radial tires used today are underinflated
just by looking at them. Therefore,
be sure to check tire pressures at least once a month and
always before going on a long trip. Make sure to take the number of
people and the amount of luggage into account when adjusting tire
pressure for a trip -even one that you would not consider to be
"long." See=>
page 242, "Tires and vehicle load limits" for more
important information.
Always use an accurate tire pressure gauge when checking and adjusting inflation pressures . Check all of the tires and be sure not
to forget the spare tire. If the pressure in any tire is too high when
the tire is "cold," let air out of the tire slowly with the edge of the tire
gauge and keep checking the pressure until you reach the pressure
that is correct for the load (passengers and luggage) and kind of driving you plan to do.
If the pressure in any tire is too low, note the difference between the
pressure in the cold tire and the pressure you need and add the air
that you need to reach the correct pressure for the vehicle load
(passengers and luggage) for the tires on your vehicle as listed on
the on your vehicle and in this manual and the kind of driving you
plan to do.
Never exceed the maximum inflation pressure listed on the tire
sidewall for any reason.
Remember that the vehicle manufacturer, not the tire manufacturer,
determines the correct tire pressure for the tires on your vehicle.
It is important to check the tire pressure when the tires are cold.
• Read the required tire pressure from the tire pressure label
located on driver's side 8-pillar.
• Turn the valve stem cap counter -clockwise to remove it from the
tire valve.
• Place the air pressure gauge on the valve.
• The tire pressures should only be checked and adjusted when
the tires are cold. The slightly raised pressures of warm tires must
not be reduced.
• Adjust the tire pressure to the load you are carrying.
• Reinstall the valve stem cap on the valve.

When should I check the tir e pressure?
The correct ti re pressure is especially i mpor tant a t high speeds . The
pressure should therefore be checked at least o nce a month and
a lways before star tin g a j ourn ey.
When should I adjust the tire pressures?
Adjust the tire pres sure to the loa d you are ca rrying. After changing
a wheel
or replacing whee ls you have to adjust the tire pressures on
a ll whee ls. In addition, y ou must the n ini tia lize the new tire pres ­
sures in the tire pressu re monitoring system*:::::,
page 253.
& WARNING
Incorrect tire pressures and /or underinflation can lead sudden tire
failure, loss of control , collision, serious personal injury or even
death .
• When the warning symbol appears in the instrument
cluster , stop and in spect the tire s.
• Incorrect tire pressure and /or underinflation can cause
increased tire wear and can affect the handling of the vehicle and
stopping ability.
• Incorre ct t ire pressures and /or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehicle control.
• The driver is responsible for the correct tire pre ssure s for all
tires on the vehicle . The appli cable pressure values are located on
a sticker on the driver' s side B -pillar.
• Onl y when all tires on the vehicle are filled to the correct pres­
sure , the tire pre ssure monitoring system* can work correctly .
• The use of incorrect tire pressure values can lead to accidents
or other damage. Therefore it is essential that the driver observe
the spe cified tire pressure values for the tires and the correct pres­
sures for the function of the tire pre ssure monitoring sy stem *.
• Always inflate tires to the recommended and correct tire pres­
sure before driving off.
& WARNING (continued )
• Driving with underinflated tires bend more , letting them get
too hot re sulting in tread separation, sudden tire failure and lo ss
of control .
• Excessive speed and /overloading can cause heat build -up ,
sudden tire failure and loss of control.
• If the tire pressure is too low or too high , the tires will wear
prematurely and the vehicle will not handle well.
• If the tire is not flat and you do not have to change a wheel
immediately, drive at reduced speed to the nearest servi ce station
to che ck the tire pres sure and add air as required .
0 Note
Driving without valve stem caps can cause damage to the tire
va lves. To prevent this, always ma ke sure that fac tor y in st alled va lve
stem caps on all wh eels are securely mounted on the valv e.
'£> For the sake of the environment
Underinflated tires w ill also increase the fue l consumption. •
Tires and vehicle load limits
There are limits to the amount of load or weight that any vehic le and
any tire can ca rry. A vehicle that is overloaded wil l not handle wel l
and is more difficu lt to stop . Overloading can not on ly lead to loss
of vehic le contro l, but can also damage important parts of the
ve hicle a nd can l ead to sudden t ire fa ilure, i nclud ing a b lowout an d
sudden deflation that can cause the vehicle to crash .

& WARNING
Overloading a vehicle can cause loss of vehicle control, a crash or
other accident , serious personal injury , and even death .
• Carrying more weight than your vehicle was designed to carry
will prevent the vehicle from handling properly and increase the
risk of the loss of vehicle control.
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe distance.
& WARNING (continued )
• Tires on a vehicle that has been overloaded can fail suddenly,
including a blowout and sudden deflation , causing loss of control
and a crash .•
Determining correct load limit
Use the example below to calculate the
total weight of the passengers and
luggage or other things that you plan to
transport so that you can make sure that
your vehicle will not be overloaded.
Steps for Determining Correct
Load Limit
1 . Locate the statement "THE COMBINED
WEIGHT OF OCCUPANTS AND CARGO SHOULD NEVER EXCEED XXX KG OR XXX
LBS "on your vehicle 's placard (tire infla­
tion pressure label)~
page 238, fig. 148.
2. Determine the combined weight of the driver and passengers that will be riding
in your vehicle. ..,
Vehicle care I t •

-Tires and wheels
3. Subtract the combined weight of the
driver and passengers from
"XXX" kilo­
grams or
"XXX" pounds shown on the
sticker=>
page 238, fig. 148.
4. The resulting figure equals the available
amount of cargo and luggage load capacity. For example, if the
"XXX"
amount equals 1400 lbs. and there will
be five 150 lbs. passengers in your
vehicle, the amount of available cargo and luggage load capacity is 650 lbs. ( 1400- 750 (5
x 150) = 650 I bs.)
5. Determine the combined weight of luggage and cargo being loaded on the
vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be transferred
to your vehicle. Consult this manual to determine how this reduces the avail ­
able cargo and luggage load capacity of
your vehicle. -
Check the tire sidewall (=>
page 246,
fig. 152) to determine the designated
load rating for a specific tire . •
Tire service life
The service life of tires depends on a lot of different things
including proper installation and balancing, correct tire
pressure and driving style.

& WARNING
Sudden tire failure can lead to loss of control , a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators.
• Worn tires are a safety hazard , they do not grip well on wet
roads and increase your risk of "hydroplaning" and loss of control.
• Always keep chemicals that can cause tire damage , such as
grease , oil , gasoline and brake fluid away from tires .
• Tires age even if they are not being used and can fail suddenly,
espe cially at high speeds . Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds .
• Never mount used tires on your vehicle if you are not sure of
their "previous history ." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control. •
